Rust

Lemon juice or vinegar remove rust stains. These are acids that react with an oxide to form a salt and water.

Iodine

Iodine is a very effective antiseptic, used in hospitals. It can also be used to purify water, 5 drops of 2% iodone solution per litre, wait 15-30 minutes depending if the water is clear or cloudy. Apparently sugar binds to the iodine so will remove the taste.

Chicken

Salmonella

Raw chicken can cause salmonella poisoning so never cut veges on the same chopping board that you have used for raw chicken. Wash the chopping board and knives with very hot soapy water.
